The League One team aim to inflict a fourth straight defeat on United in the EFL Cup at Sixfields Stadium.

Over eight days, they lost at home to Manchester City and away to Feyenoord and Watford sparking talk of a crisis for new boss Mourinho.

And Rochdale-born David Buchanan - who is set to skipper the Cobblers tonight - said: “Man United have got everything to lose.

“We are massive underdogs, we know that. We are not dressing it up any other way. We are a League One team, they are a Premier League team.

“They have got the most expensive player in the world in Paul Pogba, but what I can say is they have lost three games on the trot.

“It was a big tie anyway because everybody loves the underdog and the upset. But I think what’s happened at United over the last week or so, losing three games, means it’s just pumped up a little bit more.”

Predicted Manchester United line-up: 4-2-3-1

Buchanan, 30, a lifelong United fan, added: “Their confidence levels are going to be a little bit low and I hope they come here expecting us just to be rolled over and they take the foot off the gas a bit and hopefully we can surprise them.”

“I think losing three in a row does affect you, doesn't it? They are the highest-paid players in the world, they have the price tags that comes with that, they have the most-spoke about manager in the world, who is a winner.

“But I think for Northampton as a town and a club what has happened to Manchester United in the last week has made this game even bigger. They need to turn the corner quickly. They are Manchester United and have so many fans all around the world and they are just expected to win.

“I am sure the majority of people watching will be wanting to see a big upset. They haven’t been starting well, we’ll try and come out of the blocks at home.

“It’s a tight ground, it’ll be packed, it’ll be full of screaming fans at both ends and our fans get right behind us.

“They’ll be under pressure from the manager. He’s the biggest name in the world, he loves to win, he’s won everything in his career wherever he’s been. So I’m sure those players – it doesn’t matter who they are – will be getting a backlash off him.

“And he’ll be expecting them to come here, put a professional performance on and play like they play for Manchester United.

“But hopefully they don’t do that, and if we can capitalise we’ll make it hard for them – we’ll get the ball in behind them and whether it’s the skip (Marc Richards) or it’s Alex Revell up front, or whoever it is, those centre-halves will know they’ve been in a game.”
